DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mechanical parking device for transferring a vehicle to a parking room by relaying a traveling vehicle.

[Prior art]

[0002] Various types of mechanical parking devices have been used for some time because of their advantages such as space efficiency and operational efficiency. Among them, there are already many installation examples in which a traveling cart is used for delivery of a vehicle between a parking room and the outside because the accommodation efficiency is excellent. Hereinafter, FIG. 5 shows and describes a mechanical parking device using a traveling vehicle.

The above-mentioned mechanical parking device 1 (hereinafter, also simply referred to as a parking device) is often provided inside a building or underground. The mechanical parking device 1 is provided with an entry / exit room 2 for entering / exiting a vehicle. A plurality of parking rooms 3 are arranged in a longitudinal direction inside the parking device 1, and a traveling path 4 is provided along the parking rooms 3. A traveling rail 5 is laid on the traveling path 4, and a traveling vehicle 6 on which a vehicle is mounted can freely travel on the traveling rail 5. The traveling vehicle 6 and the parking room 3 are provided with the vehicle 8 in a direction orthogonal to the traveling path 4, that is,
The conveyors 9 and 10 (hereinafter, also simply referred to as conveyors) for moving the vehicle 8 from the parking room 3 to the parking room 3 or the vehicle 8 from the parking room 3 to the traveling trolley 6 are provided so as to be connectable.

[0004] In the parking device 1, it is also possible to form a plurality of parking floors by stacking the parking rooms 3 in order to increase the number of storage units. In this case, a traveling rail 5 is laid on the lowest floor, and the traveling carriage 6 is provided with a lift mechanism in order to exchange vehicles between the parking room located above and the traveling carriage. A traveling vehicle having this lift mechanism is referred to as a traveling vehicle with a lift. In some cases, a traveling rail 5 is provided for each parking floor, and a traveling vehicle having no lift mechanism is arranged for each floor.

[0005] Here, a traveling carriage 6 with a lift is shown in FIG. The traveling carriage 6 with a lift has wheels 6a, and the wheels 6a
To travel on the traveling rail 5. The wheel 6a is provided with urethane rubber on its outer periphery to reduce running vibration. The lifting platform 7 of the traveling vehicle 6 with a lift is a main frame.
It is guided up and down by an elevating body frame 13 having four supporting columns 12 erected at 11 as constituent members. The elevator 7 is provided with a movable frame 14 that moves in a direction orthogonal to the traveling path 4. A power transmission roller 15 is rotatably provided on a side surface of the movable frame 14 facing the parking room 3. The power transmission roller 15 and the conveyor 9 of the traveling carriage 6 with a lift
Are both driven by the drive motor 16. In addition, the movable frame 14 is mounted on the elevator 7 in a direction orthogonal to the traveling path 4,
That is, a driving unit 17 for moving the vehicle toward the parking room 3 is provided. Further, on the side of the traveling path 4 of the parking room 3, there is provided a driven roller 18 interlocking with the conveyor 10 of the parking room 3.

When the vehicle is to be parked, the traveling carriage 6 with the lift is made to reach the side of the target parking room 3 and the driving means 17 is driven.
Moves the movable frame 14 in the direction of the target parking room 3. As a result, the power transmission roller 15 provided at the side end of the movable frame 14 comes into contact with the driven roller 18 of the parking room 3 and presses it.

When the power transmission roller 15 comes into pressure contact with the driven roller 18, the drive motor 16 operates to rotate the conveyor 9 of the traveling carriage 6 with lift and the power transmission roller 15. Then, the driven roller 18 rotates together with the conveyor of the parking room 3.
The rotation is transmitted to 10 and the conveyor 9 of the traveling carriage 6 with a lift.
And the conveyor 10 in the parking room 3 rotates synchronously, and the vehicle placed on the elevator 7 is carried into the target parking room. When the vehicle is to be taken out of the vehicle, the conveyors 9 and 10 are driven in the opposite direction to the entrance, so that the vehicle can be carried out in the same manner as the entrance.

[0008]

However, the mechanical parking device having the above configuration has the following problems. The structure of the mechanical parking device 1 having the parking room 3, the traveling path 4, and the traveling rails 5 is divided into several parts in order to satisfy all of the transportability, assemblability, and assembling accuracy of parts. Into units, and each unit is produced at the factory. And transport it to the installation location in units,
The final assembly is performed at the installation location of the mechanical parking device 1. The present inventors have already disclosed details of unitization of components in Japanese Patent Application Nos. 6-192169 and 6-210429. Similarly, the traveling trolley 6 is similarly divided into several units for factory production, and these units are carried into the above-mentioned structural body for final assembly.

Therefore, it is inevitable that a slight assembly error will occur in the structure and the traveling carriage when the final assembly is performed at the installation location. Since the rails 5 are fixed in a predetermined positional relationship based on the same assembly reference position, the rails 5 are less affected by assembly errors and do not interfere with each other. However, the traveling carriage 6 with a lift moves inside the structure, and the reference position at the time of assembly is different from the structure having the parking room 3, the traveling path 4, and the traveling carriage 5. And parking room 3
When the vehicle is installed in multiple stages, the traveling vehicle 6 also needs to have a corresponding height, and the assembly error between the structure and the traveling vehicle 6 may become a value that cannot be ignored as the height increases. is there. Then, it becomes impossible to provide an appropriate interval between the parking room 3 and the traveling vehicle 6, which hinders traveling of the traveling vehicle 6. Therefore, it is necessary to set a large distance between the parking room 3 and the traveling vehicle 6 in advance. However, in this case, the interval between the conveyors 9 and 10 also becomes large, and the delivery of the vehicle between the parking room 3 and the traveling carriage 6 lacks smoothness. Was.

[0010] Further, as the traveling distance of the traveling vehicle increases,
The urethane rubber disposed on the outer peripheral portion of the wheel 6a wears, and the diameter of the wheel 6a is reduced. Then, the conveyor 9 of the traveling carriage 6
As a result, the height of the parking room 3 with respect to the conveyor 10 is shifted, which also causes a lack of smooth delivery of the vehicle.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to easily correct an assembling error between a parking room and a traveling vehicle and a change in a positional relationship due to wear. It is in.

[0012]

Means according to the present invention for solving the above-mentioned problems are as follows: a plurality of parking rooms are arranged in tandem, a traveling path is set up along the parking room rows, and the vehicle travels on the traveling path. A traveling vehicle that travels on wheels on the traveling rail is disposed on a structure on which rails are laid, and vehicles are mutually transferred by vehicle transport conveyors provided in both the traveling vehicle and the parking room. The mechanical parking device is characterized in that adjustment means for supporting the inclination of the traveling bogie frame with respect to the wheel axis of the traveling bogie so as to be changeable is provided.

[0013] The traveling vehicle frame is supported so as to be capable of changing the inclination of the traveling bogie frame with respect to the rotation axis of the wheel, and is constructed based on different assembling standards with respect to the structure having the parking room, the traveling path and the traveling rail. The inclination of the bogie frame matches the inclination of the structure.

[0014]

Embodiments of the present invention will be described below with reference to the accompanying drawings. In the figure, the same or corresponding parts as those of the conventional example are denoted by the same reference numerals, and detailed description is omitted.

FIG. 1 is a front view of a traveling vehicle 6 with a lift according to an embodiment of the present invention, and FIG. 2 is a side view of the traveling vehicle 6 with a lift. The parking room 3 shown in FIG. 1 shows an example in which three layers are stacked, and a traveling carriage 6 with a lift.
Has an ascending and descending height corresponding to the three-tiered parking room. The elevating body frame 13 of the traveling carriage 6 with a lift includes four supporting columns 12 erected on the main frame 11 and reinforcing members 19,
It is formed by connecting and reinforcing at 20. A chain 21 is hung around the elevating table 7 that is guided up and down by the elevating body frame 13 to transmit the power of the elevating motor 22. The traveling carriage 6 with a lift includes wheels 6a.
Is driven by the traveling motor 23 (FIG. 2),
It can move freely on the running rail 5.

By the way, an H-shaped steel is used for the traveling rail 5, and a guide rail 24 is formed by fixing an angle iron or the like along the side surface of the web of the traveling rail 5. On the main frame 11 of the traveling carriage 6 with a lift, a main guide roller 25 is provided below the rotating shaft of the wheel 6a (FIG. 2) so as to be guided by the guide rail 24. The traveling carriage 6 with the lift can travel along the traveling path 4 without departing from the traveling rail 5 by the traveling guide of the main guide roller 25 by the guide rail 24.

The traveling carriage 6 with a lift is provided with a sub guide roller 26. By the way, as shown in FIG. 1, the multi-stage parking room 3 has a main frame 30 parallel to the traveling path 4 placed on a unitized base 29 provided with a vertical column 28 under a horizontal frame 27. The conveyor 10 is formed on the main frame 30 in a direction orthogonal to the traveling path 4. The main frame 30 of the parking room 3 adjacent to the front and rear is continuous along the traveling path 4. The auxiliary guide roller 26 uses the web side surface of the main frame 30 as a guide rail structure. Reinforcing members 19 and 20 forming the elevating body frame 13 of the traveling carriage 6 with a lift are provided at substantially the same height as the main frame 30 of the parking room 3. 26 is attached (Fig. 2).

When the traveling carriage 6 moves on the traveling path 4, the traveling carriage 6 is basically guided by the main guide roller 25. Therefore, the interval between the guide rail 24 fixed to the side surface of the web of the traveling rail 5 and the main guide roller 25 is set so as to be a minimum interval necessary for the traveling vehicle 6 with a lift to travel. The auxiliary guide roller 26 is provided mainly for the main frame 30 of the parking room 3 when the upper part of the lifting / lowering body frame 13 bends while the traveling carriage 6 is traveling.
, And further bending is suppressed, and when the sub guide roller 26 is guided to run on the web side surface of the main frame 30, the traveling carriage 6 with lift is maintained in a stable traveling state. Therefore, the distance between the main frame 30 and the sub guide roller 26 is set to a distance that does not normally contact.

Next, a description will be given of the adjusting means for supporting the inclination of the traveling vehicle frame with respect to the wheel shaft 31 of the traveling vehicle 6 so as to be changeable. In addition, the traveling bogie frame is,
1 shows a frame of a traveling vehicle formed by a main frame 11, a support 12, a reinforcing members 19 and 20, and the like.

As shown in FIG. 1, the left and right wheels 6a are supported at both ends of a wheel shaft 31. The wheel axle 31 is attached to the traveling bogie frame (specifically, a support plate 3 fixed to a portion where the main frame 11 and the support 12 shown in FIG. 2 intersect).
2, 33), and are fixed via adjustment bearings. 3 and 4 show the adjusting bearing 34. FIG. The adjusting bearing 34 includes a radial bearing 35 and a flange plate 36, and uses a bolt 37 and a nut 38 to support the support plate 32,
33 is pinched. The flange plate 36 is bolted to the wheel shaft 31
A flat plate portion 361 having a circular hole formed therethrough and a flange portion 362 having a surface orthogonal to the flat plate portion 361. Further, as shown in FIG. 4, the support plates 32 and 33 are formed with a vertically long oblong shaft hole 39 and a bolt hole 40 for allowing the wheel shaft 31 and the bolt 37 to pass therethrough. Further, projections 32a, 33a are formed on the support plates 32, 33, and the head of the adjustment bolt 41 screwed with the projections 32a, 33a.
411 is in contact with the flange portion 362 of the flange plate 36. In addition, as shown in FIG. 1, the adjustment bearing 34 is adopted only in one of the two left and right bearings that support the wheel shaft 31.
The other is a normal radial bearing without adjustment means.
It is supported by.

The following procedure is used to change the inclination of the traveling bogie frame with respect to the wheel shaft 31 by using the adjusting means having the above-described configuration. First, the bolt 37 and the nut 38 are loosened to release the fixing of the adjustment bearing 34 to the support plates 32 and 33. Next, the adjustment bolt 41 is rotated. Then, the heads of the adjustment bolts 41 with respect to the projection pieces 32a and 33a.
The protrusions 32a and 33a are guided by the spiral groove of the adjustment bolt 41 and move up and down with respect to the flange 362 by the action of the 411 moving forward and backward. Then, the support plates 32, 33 to which the projecting pieces 32a, 33a are fixed are moved up and down. The movable range at this time is from the upper end of the shaft hole 39 to the lower end of the shaft hole 39. As described above, the other radial bearing supporting the wheel shaft 31
Since 42 (see FIG. 1) has no adjusting means, the adjusting bearing 34
By appropriately moving the support plates 32 and 33 having the side up and down, the angle formed by the traveling bogie frame and the wheel shaft 31 about the radial bearing 42 as the center of rotation can be changed.
Then, when the desired inclination angle is obtained,
Tighten 37 and nut 38, and adjust bearing 34 to support plate 32,
Fix to 33.

The operation and effect obtained from the embodiment of the present invention having the above configuration are as follows. By supporting the inclination of the traveling bogie frame with respect to the wheel shaft 31 of the traveling bogie 6 so as to be changeable, assembly errors between the structure having the parking room 3, the traveling path 4, and the traveling rail 5 and the traveling bogie 6 are large. (For example, when the structure is assembled without distortion and the traveling bogie frame is deformed into a parallelogram as viewed from the direction shown in FIG. 1 and assembled).
However, the parking room 3 and the traveling vehicle 6 are tilted by tilting the traveling vehicle frame in accordance with the assembly state of the structure.
It is possible to provide an appropriate interval between them. That is, it is possible to easily correct an assembling error between the traveling body 6 and the structure having different assembly reference positions. Accordingly, there is no danger that the sub guide roller 26 of the traveling vehicle 6 will come into contact with the main frame 30 of the parking room 3 with an excessive force.

Incidentally, it is also possible to mount adjustment bearings 34 for supporting the inclination of the traveling bogie frame with respect to the wheel axle 31 so as to be changeable, on both the left and right sides of the wheel axle 31. In this case, the adjustment of the inclination angle of the traveling bogie frame is performed by fixing one of the left and right adjustment bearings 34 and moving only the other adjustment bearing 34.

The advantages of using the adjusting bearings 34 on both the left and right sides are as follows. FIG.
As shown in the figure, the wheels 6a of the traveling carriage 6 with a lift are provided with urethane rubber on an outer peripheral portion 6b thereof to reduce traveling vibration. Therefore, when the traveling distance of the traveling vehicle increases,
The wheel outer peripheral portion 6b is worn, and the diameter of the wheel 6a is reduced. Then, the traveling trolley frame sinks in the parking room 3 by the diameter of the wheel 6a, and the height of the conveyor 9 of the traveling trolley 6 and the height of the conveyor 10 of the parking room 3 are shifted.
Delivery of vehicles between each other lacks smoothness.
At this time, by adjusting the left and right adjustment bearings 34 in the direction in which the traveling bogie frame is raised with respect to the wheel axle 31, the diameter reduction due to the wear of the wheel outer peripheral portion 6b can be corrected.

In the case of the traveling carriage 6 with a lift, the elevator 7
It is possible to correct the diameter reduction due to the wear of the wheel outer peripheral portion 6b by controlling the stop height of the vehicle, but it is possible to use a traveling vehicle having no lift (the traveling vehicle is arranged for each parking floor). Type) mechanical parking device,
In the past, there was no other way but to replace the wheels, which is particularly effective.

[0026]

According to the present invention, the following effects are obtained. Supporting the inclination of the traveling bogie frame with respect to the rotation axis of the wheel so as to be changeable, the parking room,
The inclination of the traveling bogie frame assembled on the basis of the separate assembling reference position with respect to the structure having the traveling path and the traveling rail can be made to match the inclination of the structure. Therefore, it is possible to easily correct an assembling error between the structure and the traveling vehicle and a deterioration of a positional relationship due to abrasion, and to adjust to an optimum state. Therefore, traveling of the traveling vehicle can be performed safely and securely, and the setting of the interval between the parking room and the traveling vehicle can be optimized, so that the vehicle can be moved between the parking room and the traveling vehicle. Delivery can be performed smoothly.
